Function Documentation

template<class T >

size_t VtHashValue

(

T const &

val

)

Compute a hash code for val by invoking (hboost::)hash_value(val) if possible, otherwise by invoking TfHash()(val), or if neither are possible issue a coding error and return 0.

template<class T >

constexpr bool VtIsHashable

(

)

A constexpr function that returns true if T is hashable via VtHashValue, false otherwise. This is true if we can either invoke (hboost::)hash_value() or TfHash()() on a T instance.
